Developers of Willowcreek Ranch, a master-planned community outside of Tomball, are rolling out the second phase of inventory half a year earlier than originally planned because of high demand for the homes in the community.

Houston-based Caldwell Communities said in a statement that 90 percent of its Phase I homes released in November 2013 have already sold. The first homes in the community, along Texas 249 and a future expansion of the Grand Parkway, are slated to be completed by fall 2014. Because of demand, the predeveloped Phase II lots will be available for sale. The grand opening for those homes will be in May, but private tours are already available.

Asking prices for homes in Willowcreek Ranch start at $600,000 and rise into the millions. Lots range from one to seven acres and the property will include a 40-acre lake, an equestrian center and seven miles of hiking and riding trails.

The master-planned community is part of the growth of the area near The Woodlands, where Exxon Mobil’s new campus has influenced massive expansion of residential and commercial properties. For more on what’s happening north of Houston, read the Houston Chronicle’s piece on the Exxon Mobil effect.
